i bought one of these for my sony duo vaio ultrabook since it doesnt come with onboard ethernet. i bought this originally because of the small footprint and the "diamond" name. the ethernet works great, but my only problem with this device is that it seems to cause some interference with my logitech anywhere mouse. when i have my logitech usb dongle connected directly to the laptop's usb port and the diamond adapter in the other usb port, my mouse is occasionally erratic, it stutters, or stops partially and i have to lift it and move it closer to the dongle. it seems to be less erratic when the logitech usb dongle is connected to one of the usb ports on the adapter though. if i completely remove the adapter then the mouse behaves normally. so i think somehow this device is causing interference. i am going to have to live with it though, but its far from ideal.

i'm tempted to buy the diamond docking station that is now being sold also, but what has held me back is the problem i am having with the erratic behavior of my wireless mouse. because ideally i still need something for the office for my dual monitors.

but as for portability, this adapter still gets the job done as long as i am not too dependent on my mouse, which is ok in my case since i have a touchscreen win8 device. i can see how the interference wouldn't be noticeable on a mac also, since you can get by just using the mousepad.

Received goods in good condition, thumbs up for DHL great service, received less than expected delivery time as well.

Review:
Hardware:
Laptop: Lenovo G400s (Windows 8.1)
Switch: Cisco Gigabit switch
Server: Just another high-end server

The Good:
Gigabit LAN works without any driver installation, plug-n-play.
Works up to the advertised performance.

The Bad:
Stiff USB3 cable, but it does not really bother me too much.
USB3 hub ports on the case is not aligned properly with the port, plugging in USB plug require a little effort.

Tested with (All plugged in):
- Gigabit LAN,
- USB 3.0 pendrive (Team Extreme USB3 64GB)
- USB 2.0 pendrive (Sandisk Cruzer 16GB)
- USB 2.0 external hard disk (Seagate 320GB).
Gigabit LAN sustained transfer speed (from laptop to server): 102 MB/s
USB3 pendrive max write speed: 26 MB/s
USB2 pendrive max write speed: 4.5 MB/s
USB2 external hard disk max write speed: 36 MB/s

Great performance, has no regret paying for its price.

Works perfectly on 2013 MacBook Air with USB 3.0. No issues. Would highly recommend this device. It's small enough to fit nicely in a small backpack with the laptop.

I ordered this item for my daughter to use in her college dorm. The dorm has poor WiFi but has wired ethernet connections. She has an Apple MacBook Air that doesn't have an Ethernet port. I had this delivered to her and I talked her through the installation. The only issue was the need to install a driver from a CD (included with the product). Once the driver was installed and laptop rebooted, the device provided the network connection.

I'm an IT guy, but my daughter needs help turning on the laptop! If we can install this over the phone, anyone can do it.

The product works as advertised and my daughter is happy.

Ethernet port doesn't work. Invalid BOS descriptor (whatever that is).
Will update rating if they get back to me and resolve this. Otherwise, I'm sending it back.

update:7-12-14
Support is BAD. Their website says to give them 24-48 hours to respond: it's been 5 working days. I have left periodic messages asking for an update to no avail.
My last post to their ticketing system said if I don't hear back today to know that they are at least working on it, I'm returning it as defective.

The product did not work. Not only was it tested on my PC, but it was also tested on 5 other PCs by computer repair technicians. I bought an earlier version circa two years ago that did work. This earlier version came with a CD that was used to install drivers. The newer version apparently has firmware that is supposed to install drivers, but doesn't .
